•All measurements are done on a calibrated coupler

B&K 4153 (artificial ear) with the standard cone

YJ0304 above the adapter plate, type DB 0843.

•The pressure of the headband shall be 10N ± 1N.

•The RMS input voltage to the headphone is 0.5 V.

•The measurements are done with steady state sine

wave signals.

•The output impedance of the signal source shall be

<1 Ohm.

•Climatic conditions:
